VALVE FOR PLUMBEBS FURNACES.

Specification of Letters Patent. P t t d J y 1 1916 Application filed February 251913 Serial No. 750,466. i

To all whom it may concern: 1

Be it known that I, ALBERT E.'BACON, a citizen of the United States, residing-at Germantown, in the county of Philadelphia,

is inclined to the vertical. The valve mem ber 6 .as shown in Fig. '2 is provided with the, apertured lug 11, the aperture or chan ml 12 of which is adapted to communicate with the aperture 13 leading to the fuel tank 10, said communication being controlled by the valve 7. Into lug 11 is threaded the aperturednozzleij, which is adapted to engage the end of the rubber tube 4.. This, nozzle member; 5 has an enlarged channel 14, in the threaded portion thereof, communicating with the channel 12. This channel 14 is preferably provided with the concave end 17 which is in communica tion with the aperture or opening 16 of channel 18. Into this concave part 17 and the aperture 16 the ball 15, is adapted to seat, so as to close communication between channel 18 of said nozzle and the channel 12 of the lug. The inclined position of valve member 6 and lug 11 is such that the ball 15, by the force of gravity, will normally lie against the entrance to channel 18 and maintain the same closed. The pressure from the reservoir will render such closure effective. adapted to yield to pressure exerted by the pump to permit the passage of air past the ball to the reservoir. By this means whether the pump 3 or tube l becomes defective or not, the ball will always prevent the escape of fuel gases from nozzle 5, and thus prevent the accidents above referred to.

Vhen it is desired to relieve the air pressure in fuel reservoir, when through using the furnace, and after the fire is extinguished, valve is closed, and the furnace tilted to elevate the aperture 16 above the recess 12, whereupon the ball will be carried by gravity away from the aperture 16. By then moving the valve 7 to open position the air confined in reservoir 10 is permitted to escape.

In filling the reservoir the thumb screw cap 20 is removed and the gasolene poured in the opening. If the gasolene is poured in very fast it will be necessary for the air to escape from the reservoir 10 through some other opening than that through which the gasolene enters. This may be provided for by arbitrarily unscrewing the nozzle member 5 until the passages 19, as shown in Fig. 3, establish communication between channel 2 a e outside at p e e With he and useful Valve for Plumbers Furnaces, of which the following is a specification.

My invention relates to improvements in plumbers furnaces.

The object of the invention is to provide a safety device in connection with means for pumping air into the fuel reservoir of said furnace. Heretofore it has been customary to provide a rubber bulb pump and rubber tubing connected with the nozzle of a valve controlled cock communicating with the fuel reservoir; the practice being to open the cock and pump the air to the necessary pressure in the reservoir, and then close the cock. After the furnace is lighted, it becomes necessary from time to time to open the cock again, and pump more air into the reservoir. It happens, that in time the rubber tubing deteriorates and sometimes breaks or is blown off the nozzle by the pressure in the reservoir, and the escaping fuel gases ignite from the furnace causing se rious accident to the one operating the same. These accidents have frequently happened in the past and to prevent occurrences of a similar character, is the object of the present invention.

Referring to the drawings, which illustrate merely by way of example, a suitable embodiment of my invention-Figure 1 is a view in elevation of a standard plumbers furnace to whichmy invention is applied. Fig. 2 is a vertical section of the valve controlled nozzle embodying my invention. Fig. 3 is a fragmentary cross-section transverse that shown in Fig. 2, to show the channels 19.

Similar numerals refer to similar parts throughout the several views. I Referring to Fig. 1, 3 indicates the rubher pump bulb, 4: the rubber tubing connecting the same with the nozzle 5, secured in the valve member 6. This valve member 6 is controlled by the ordinary needle valve 7 operated by the hand wheel 8. This valve member 6 is tapped into the inclined surface 9 of the fuel reservoir 10, having its longitudinal extension at right angles with the inclined surface 9. When the furnace i in the upright position as shown Fig.

1, itwill be seen that the valve member 6 The ball 15 however is nozzle in this position and valve 7 in the open position, it will be seen that the air can freely escape through the passages 19. This method may also be used for relieving the pressure of air in reservoir 10 when through using the furnace.

What I claim is 1. A valve comprising a. channeled body having a main extension, a lug projecting from and substantially at right angles with the main extension, said lug having a channel communicating with the main channel and provided with a threaded open end, a channeled nozzle having an exteriorly threaded end for disengageable connection with the lug, said threaded end provided with an enlarged semispherical opening communicating with the nozzle channel and forming a ball receiving chamber, and a ball Copies of this patent may be obtained for in said chamber normally maintained in channel closing position by gravity.

2. A valve comprising a channeled body having a main extension, a lug projecting from and substantially at right angles ith the main extension, said lug having a channel communicating with the main channel, a channeled nozzle connected with said lug, a valve seat, a ball normally seated therein for controlling communication between the channels in the nozzle and the lug, and a radially extending channel in the threaded end of the nozzle as and for the purpose specified.

ALBERT E. BACON.
